5 Claims.

and more particularly to Ventilating apparatus which is adapted to be arranged within the space defined by a partially raised window sash and a window sill.

My invention has for an object to provide an improved means for supporting and leveling i Ventilating apparatus of the window-mounted type.

The invention consists in the novel construction and combination of parts, to be more fully described hereinafter, and the novelty of which will be particularly pointed out and distinctly claimed. y

In the accompanying drawings, to be taken as a part of this specification, I have fully and clearly illustrated a preferred embodiment of my invention, in which drawings- Fig. 1 is a transverse vertical sectional view showing one preferred form of my improved window ventilator as mounted in a window opening,

' the section being taken on the line of Fig 2;

Figl 2 is a plan view of the structure shown in Fig. 1, the rear or outside of the ventilator being partially broken'away to disclose the interior structure thereof; and

Fig. 3 is a fragmentary detail sectional view illustrating one preferred form of a supporting and leveling device carried by the outside or rear portion of the ventilator.

Referring now in detail to the construction illustrated, it will be observed that I have shown Aa ventilator IU as arranged within an opening dened by a lower sash rail of a window sash I2 and a window sill I3, the ventilator being supported by the sill I3. The window construction is of conventional form and comprises, in addition to the window sash and sill just described, vertically disposed jambs I4 in which thewindow sash I2 slides. Filler blocks l5 are arranged at each side of the ventilator and serve to close the spaces between the ends of the ventilator and the window jambs.

A sealing member I6 extends longitudinally of the ventilator in the general plane of the Window sash l2 and is secured to the ventilator by any suitable means such, for example, as spot welding. The member I6 comprises a horizontal flange i1,

Ya vertical ange I8 and sealing material I9 secured to the flanges and engaged by. the lower sash rail I I of the sash I2. In the proper installed position of the ventilator I0, the Vertical ange I8 is arranged parallel to and adjacent the `inside lower face of the sash rail (see Fig. 1).

The ventilator I0 comprises a casing 20 having My invention relates to Ventilating apparatus,

an inlet opening 2| in the rear part thereof and a pair of outlet openings 22 and 23 in the front and-top parts, respectively. The inlet opening 2| is provided with flxd louvers 24 for preventing the entrance of waterand snow into the ventilator. The outlet opening 22 is provided with adjustable louvers 25 for closing the opening or for directing the air to different desired portions of the room forwardly of the ventilator. The outlet opening 23 is provided with adjustable louvers 26 which serve either to close the opening or to direct the air from the ventilator upwardly from the ventilator, as desired.

Arranged within the ventilator is a longitudinally extending upright partition 21 dividing the ventilator intoan inlet chamber 28 communicating with inlet opening 2| and anvoutlet chamber 29 communicating with the outlet openings 22 and 23. Openings 30 are provided in the partition 2l and a motor blower unit 3| is arranged within the inlet chamber 28 and operates to draw fresh Aair from the outside through they inlet opening 2| and chamber 28 and to force such air into the room through the openings 30, the out-l let chamber 29 and the outlet openings 22 and 23. A longitudinally extending damper 32 is provided for preventing the flow of air through the ventilator when the motor. blower unit is not leveling the ventilator inan opening dened by the partially .raised window sash I2 and a win dow sill ,|3. The window sill vI3 comprises an inside portion or stool 34 and an outside portion Yor saddle 35, the latter being at a lower level than the inside portion 34 and sloping outward and downward to shed rain and snow. The ,venti- ,lator I0 is supported at its front or inside portion by theA inside sill portion 34 and is preferably positionedfso that its center'of gravity, in-

dicated by theline A, is at the rear or outside of the inside'sill portion 34. .y

The ventilator is secured to 'thejy inside sill -portion 34 by suitable angle brackets`38 carried by the ends of the ventilator and screws 39 `threaded into :the sill portion 34. A strip of felt -or other sealing material Ml is arranged longitudinally of the ventilator and between the bottom thereof .and the inside sill portion 3 4.' The 2 device 43 fixed to the inside rear of the ventilator.

There are two jack screws 42 shown, one being at each end of the ventilator.

In addition to the function of carrying the unsupported weight of the ventilator, the jack screws 42 may be adjusted vertically to level the ventilator and to properly position the flange I8 and the sash rail From examination of Fig. 3, it will be observed fthat the nut device 43 comprises a pair of parallel spaced members 50 and 5| joined together at one side by a third member 52. The member 50 is xedly secured to the inside and bottom of the ventilator I by any suitable means such, for example, as spot welding. The members 50 and are provided with aligned screw threaded openings 53 and 54, respectively, which are arranged in horizontal planes and receive the jack screw 42. The-members 50 and 5| are also provided with aligned openings 55 and 56, respectively, the opening 55 being screw threaded. A locking screw 51 loosely fits the opening 56 and threadedly engages at its lower end the opening 55 in the member 50.

Theoperation of the jack screw 42 will be ap- I vparent from the above description. When the jack screw has been adjusted so that the ventilatoris properly leveled and supported at the rear by-the outside sill portion and the ange I8 at the inside rear face of the rail the locking screw 51 may be turned until the head thereof engages and moves the outside part of the member 5| relatively to the member 50 and jams the mating threads of the jack screw and the openings 53 and 54, thereby preventing further turning of the jack screw.

From the above description, it will be apparent that I have provided a very simple, inexpensive and effective method of supporting and leveling window ventilators in window openings. The ventilator cannot be moved forward or backward on the window sill due to the brackets 38 `and screws 39. 'I'he weight of the ventilator is carried by the inside window sill 34 and by the outside sill 35 through the jack screws 42. The jack Y screws are readily accessible by raising the window sash |2 and then raising the rear portionv 59 of the top of the ventilator which is suitably hinged at 60 and carries at its forward longitudinal edge the sealing member I6.

What I claim and desire to secure by Letters Patent of the United States is:-

l. The combination with a window comprising upright jambs, a window sash slidably mounted in the jambs and a window sill including an inside sill portion and an outside sill portion at a lower level than said inside sill portion; of a ventilator comprising a casing structure adapted to be arranged within the window opening with a front part supported by the inside sill portion and a rear part overhanging said outside sill portion; said casing including a cover member hinged along one side so that it may be readily opened and access may be had to the rear interior thereof; and adjustable supporting and leveling means arranged within the rear of the ventilator and accessible only from the interior thereof when the cover is opened, and including an adjustable part extending downwardly through the bottom of the casing and engaging the outside sill portion for supporting the rear part of the ventilator from the outside sill portion.
